In 2001, a team of Israeli, German, and Indian scientists discovered that the majority of Jews around the world are closely related to the Kurdish people -- more closely than they are to the Semitic-speaking Arabs or any other population that was tested.

Ashkenazic Jews have ancestors who lived in central and eastern Europe, while Sephardic Jews have ancestors from southwestern Europe, northern Africa, and the Middle East. The Kurdish Jews and Sephardic Jews were found to be very close to each other. Both of these Jewish populations differed somewhat from Ashkenazic Jews, who mixed with European peoples during their diaspora. The researchers suggested that the approximately 12.7 percent of Ashkenazic Jews who have the Eu 19 chromosomes -- which are found among between 54 and 60 percent of Eastern European Christians -- descend paternally from eastern Europeans (such as Slavs) or Khazars. But the majority of Ashkenazic Jews, who possess Eu 9 and other chromosomes, descend paternally from Judeans who lived in Israel two thousand years ago.

In the article in the November 2001 issue of The American Journal of Human Genetics, Ariella Oppenheim of the Hebrew University of Israel wrote that this new study revealed that Jews have a closer genetic relationship to populations in the northern Mediterranean (Kurds, Anatolian Turks, and Armenians) than to populations in the southern Mediterranean (Arabs and Bedouins).
